The tradition of boiling at least three eggs at a time to nullify blood spots is not explicitly mentioned in halachic sources like the Shulchan Aruch.

The halachic principle of "chai nosei et atzmo" states that a living being carries itself, exempting the carrier from certain Biblical prohibitions of carrying on Shabbat.

The OU Press recently released two significant works: "The Concise Code of Jewish Law," a practical guide to observing Shabbat and other halachic laws in a clear and concise format, updated with insights from recent rabbinic authorities; and "Chumash Mesoras Harav: Vayikra," edited by Dr. Arnold Lustiger, offering a comprehensive commentary on the book of Vayikra based on the teachings of Rabbi Joseph B. Soloveitchik.
